I've been attempting to get my card working with both video input methods, using the double driver solution mentioned on various threads here. This means:

cx88_dvb for HDTV through Over the Air ATSC digital signal (RF Coax input).

v4l2_common for Standard-Def (SDTV) from my DirecTV box with following connections:

Either RCA composite or S-Video for the Analog Video signal

Red/White RCA->3.5mm jack cable going into the audio-in port of the 5500

I've tried connecting the loop cable on my card to line-in, however I get *really* bad crackly audio through this method (see link reference 1... (thanks buggy snd_hda_intel)). From reading threads about this in various places here, it seems this either may or may not be possible when using the analog input (see thread references 2->5).

However, I have had no such luck using "alsamixer -c 1" and setting the
5500's Conexant Cx8801 to capture (the Cx88 is card #1, my onboard ALC888 is card #0).

I think that this confusion is generated by people's interchangeable use of the words: analog, composite, s-video, etc...
Some threads say: Analog = v4l=possible to get audio from card (but what *input* are they using??)
Others say: With *certain* inputs --> not possible to get audio through DMA

As a budding electrical engineer, this is making me confused as to if it's possible to actually get audio through DMA when using the S-Video & analog audio jack on this card. In reality, here's how the input connections map to the words "Analog" or "Digital".

Due to the many terms and connectors used for A/V signals, this leads to a "BIG MESS":
Bolded connections are supported on the pcHDTV 5500

Analog:

Video

S-Video

RCA Composite (Yellow)

Analog RCA Component (Red, Green, Blue)

RF Coaxial (with Analog NTSC signal)

VGA

Audio

RCA Audio (Red/White)

RF Coaxial (with Analog NTSC signal)

3.5mm stereo jack

Digital:

Video

RF Coaxial (with Digitally encoded high-def ATSC signal)

HDMI

DisplayPort

DVI

Digital RCA Component (Y'CbCr)

Audio

S/PDIF

HDMI

DisplayPort

TosLink (fiber optic)

"HD" Video supporting connectors:

HDMI

Output

Usually locked down by HDCP

DisplayPort

Not in wide adoption yet, standard still being worked on (competing w/HDMI)

Output or Input (can go from device->display or internally chip->chip)

Possibly locked down by HDCP or DPCP

DVI

Output

Possibly locked down by HDCP, though not usually (as of this writing)

RF Coax (with ATSC encoding)

Input

Locked down by the "Broadcast Flag", though some tuner cards choose to not follow this

It's not possible to record from the line in. The line in is just a pass-through to
the line-out. The 5500 can only record analog audio from the RF coax input using the tuner.

xyzzy:

Can you confirm whether your statement about the 5500 also applies to the 3000? I ask because I am trying to setup my system in the same way. Is the audio input on the card able to be recorded? If not, then what is the point of using your eeprom update utility to enable the audio chip?

The 3000 is the same as the 5500. You can use the audio function to record the audio from analog TV from the RF input. Which isn't all that useful now that the digital change over has happened.
